APPARATUS FOR MECHANICALLY HANDLING DOUGH DURING PROVING Filed June 27, 1930 2 Sheets-Sheet 2 1 f' According to this Patented (let. 1931 srATEs PATENT, tame JAMES ELLIOTT WILSON, SAMUEL MCCONNELL, ANDCAMPBELL snowmen I BELFAST, IRELAND rrAnAr'Us'roit MECHANICALLY HANDLING DOUGH DURING PROVING Application filedJun 27, 1930, SerialHo. 464,204, and in Great Britain September 10, 1929.

I In bread making, thedough is taken from themlxer or kneader into each ofa number of separate receptacles or: kneaded in movable I receptacles in which the dough is proved,

' 5 the receptacles being removable to aposition toreceive (or knead)'theidough and, during proving, to' a position at which the dough is discharged to a divider or weighing machine. It-isiusual to take thedough from one prov- I ing receptacle to another to effect what is known in the tradeas cutting back. Thesereceptacles are usually mounted on wheels which run alongrthe flooroi' the bakery, causing very great wear and tear on the floor and a heavy upkeep" costs, and the dough has also be ita'kenbyhand-from one receptacle to ianother duringthe-cuttingback operation;.iThis inventionhas for its object the elimination of human handling and to pror351 2 was further automatic more-hygienic and efficient means for; carrying out the known 1 process and practice of bread (andthe like) "manufacture Y I invention, the dough proving receptacles are supported from over,- *head railsjor runways,- of any suitable con- 'struction and are carried by oneorfmore trolleys running on=said rails or runways,

, -which latter arearranged at a suitable height .3 above the floor so thatthedough receptacles 7 can be carried along clean'of'the' floor, the dough receptacles being,- preferably, each so :made that they can befdischarged through the bottom thereof; The- .runways 0r rails are i 5v so shaped and arranged as to ,carry'th'e dough proving receptacles from the point where they are filled to a suitable position for discharging their contents either into another receptacle, as hereinbeforedescribed, or into i 4b a discharge hole or chute in the floor, lead- 'ing to the measuring or'weighing machine and (or) divider; For'the purpose of providing for cutting back of the dough by discharging same fromo'ne receptacle into another receptacle, means are provided for raisl 7 ing either a section'oftherail and receptacle, orfthe receptacle itself-,by-suitable lifting gear so as to 'raise said portion of the rail" and (or) receptacle'itofahei-ght sufficient to permit of another 1 re eptacle; from another portion of the runway to be brought into position, on rails or runways, below the raised receptacle, whereby'the contents of the latter can be discharged into the receptacle below, thereby cutting back the dough from one receptacle to another. The receptacle to which the dough has been delivered from another receptacle, as described, is then moved back, or otherwise moved, clear of the raised receptacle, whlch can be lowered to normal position again, the rail, it raised, being i brought back to its normal plane so that the, empty receptacle thereon can be run back on tothe fixed runway rails and moved again to the filling position. Meanwhile the" receptacle which has been filled with the cut bac dough, is moved along the runway system,

being taken round same as long as desired and then to the position for emptying into the hole or chute in the floor leading to the dough 'vid'er.

'measuring or weighing device and (01') dif The arrangement of the fiized runway rails above the floor may be as desired to givethe required length of time between the filling of a receptacle and its final discharge. The time of proving can, of course, alsobe regulated by the speed at which the receptacles I system for a moderate sized-bakery andshowing'the receptacles in different positions onthe runway.
